I have an 04 f350 with 108000 miles on it. Truck runs great (or was) I installed and egr delete over the weekends and a new diamond eye 4" turbo back exhaust. Just got it all put back together last night and now I have a p0282 and a P0284. I know what the codes mean I just can't figure out why I am getting them all of a sudden. Talked to my buddy at ford his first answer you probably need a new injector. Seems weird that it was fine and now after egr delete it instantly goes bad. Any ideas or suggestions would be so greatly appreciated. I thought about unplugging harness from ficm and checking for maybe bad wires, But i have never done this before and am a little intimidated that I might make something worse.
